Long-term pulmonary sequelae in children who were treated with extracorporeal membrane oxygenation for neonatal respiratory failure.

Objective: Extracorporeal membrane oxygenation (ECMO) is a life-saving therapy for neonates with intractable respiratory failure, but the long-term pulmonary outcome is unknown. Our aim was to investigate the long-term pulmonary sequelae of these children.

Study Design: We studied 50 children at 11.

Identification of novel and rare mutations in California Hispanic and African American cystic fibrosis patients.

In ethnic heterogeneous California, complete genetic information is currently lacking to build solid population-based cystic fibrosis (CF) screening programs because a large proportion of mutations in the cystic fibrosis transmembrane conductance regulator gene (CFTR/ABCC7) are still unknown, especially in non-Caucasian patients. A total of 402 [46 African American+356 Hispanic] Hispanic and African American patients from California CF patient registry were included in this study. Patients with at least one unidentified mutant allele were asked to donate blood samples for further analysis, first by Genzyme Genetics for a panel of 87 known mutations, followed by temporal temperature gradient gel electrophoresis (TTGE) scanning of the entire coding exons of CFTR gene.

Preoperative polysomnograms and infant pulmonary function tests do not predict prolonged postoperative mechanical ventilation in children following scoliosis repair.

Our objective was the identification of children with scoliosis at higher risk of prolonged postoperative mechanical ventilation (MV) permits improved pre- and perioperative respiratory care to reduce postoperative complications. Pulmonary function testing (PFT) predicts prolonged postoperative MV in children who can reliably perform PFT, but some children cannot perform PFT. The objective of this study was to determine if polysomnography (PSG) or infant pulmonary function testing (IPFT) could predict prolonged postoperative MV (defined as MV >3 days) in children undergoing scoliosis surgery who could not reliably perform PFT.

Maximal expiratory flow at FRC (V'maxFRC): Methods of selection and differences in reported values.

We compared three methods of reporting maximal expiratory flow (V'maxFRC) measured in partial expiratory flow-volume curves (PEFVCs) at the point of functional residual capacity (FRC). PEFVCs were obtained with the rapid thoracoabdominal compression technique (RTC) on a total of 446 occasions in 281 HIV-negative, asymptomatic infants (4.8-28.

Chronic radiographic lung changes in children with vertically transmitted HIV-1 infection.

Objective: We prospectively studied children with and without maternally transmitted HIV-1 infection born to mothers infected with HIV-1 to determine the incidence of chronic radiographic lung changes (CRC) and to correlate these changes with clinical assessments.

Subjects And Methods: Between 1990 and 1997, we scored 3050 chest radiographs using a standardized form. Group I children (n = 201) were HIV-1-infected at enrollment.
